I've heard that the Nickies are a good product (I didn't mean put them in the 'worthless' basket with boat tailing etc) and if you need to replace your P&Cs and you see the value, then fair enough - but it's a lot of $$$ to save a few pounds...
80 KILO ROLL CAGE (175lb)? Did you find some left-over Sydney Harbour Bridge girders somewhere?
